Anthurium plant named ‘ANTHISXI’

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHISXI’ particularly characterized by having red spathes, a white spadix with a green tip, a long straight peduncle, little shoot formation, a tall plant habit and green foliage, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHISXI’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHISXI’. The new variety originated from a hybridization made in July 2004 in Bleiswijk, The Netherlands. The female parent is a red Anthurium cutflower plant designated ‘5139-08’ (unpatented), and the male parent was a red Anthurium cutflower plant designated ‘3282-06’ (unpatented).

A single plant was selected in July 2007 and has been asexually reproduced repeatedly by meristem tissue culture in Bleiswijk, The Netherlands over a seven-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in Europe on Jun. 10, 2014. ‘ANTHISXI’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands.

-   -   1) Red spathe;     -   2) White spadix with green tip;     -   3) Long straight peduncle;     -   4) Little shoot formation;     -   5) Tall plant habit; and     -   6) Green foliage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 300-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in 2014.

FIG. 3 shows three spathes at different stages of development.

FIG. 4 shows the upper leaf surface.

FIG. 5 shows the lower leaf surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHISXI’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 300-week old plants which were planted from tissue culture in 7-centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in September 2014. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001)

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHISXI’ differs from the female parent plant ‘5139-08’ (unpatented) in that ‘ANTHISXI’ has a firm, sturdy stem and a white spadix with a green tip, whereas ‘5139-08’ has a shaky and curved stem and a white spadix with a yellow tip.

‘ANTHISXI’ differs from male parent plant ‘3282-06’ (unpatented) in that ‘ANTHISXI’ has a firm, sturdy stem and a round spathe, whereas ‘3282-06’ has a firm but curved stem and an oval spathe.

‘ANTHISXI’ differs from commercial variety ‘Tropical’ (unpatented) in that ‘ANTHISXI’ has a firm, sturdy stem, small leaf size and a relatively thin and short spadix, whereas ‘Tropical’ has a stem that is often curved, large leaf size and a thick and long spadix.

‘ANTHISXI’ differs from commercial variety ‘ANTHAQAL’ (unpatented) in that ‘ANTHISXI’ has a thin and short spadix, small leaf size and light green spadix tip, whereas ‘ANTHAQAL’ has a thick and long spadix, intermediate leaf size and yellow spadix tip.
